Description
Technical field
The present invention relates to a kind of detection method that guarantees the viscose filament yarn dye uniformity.
Background technology
Viscose rayon is an important kind in the man-made fiber, and its attribute is regenerated celulose fibre.Viscose rayon comprises viscose filament yarn and short rayon fiber.Viscose filament yarn is the good textile raw material of a kind of wearability, textile take it as raw material have good moisture absorption, ventilative, soft, smooth, dangle, dyeability that gloss is beautiful and good and the characteristics such as antistatic, be the main yarn raw material of field of textiles.
The dye uniformity of viscose filament yarn is the important indicator of the long quality of evaluation viscose glue, also is the key element of weighing enterprise's field management level and technology.The dye uniformity of viscose filament yarn is divided into 5 grades, and 5 grades are the highest, no color differnece, and other successively decreases.GB/T13758-2008 national standard and FZ/T54011-2006 textile industry standard, separate provision evaluation methods and the classification standard of viscose filament yarn and continuous spunbond glue filament dyeing uniformity coefficient grade.High-class product is 〉=4 grades (aberration 0.8 between each cylinder or the spinning cake) of dyeing ash card, and Grade A is 〉=3.5 grades (aberration 2.5 between each cylinder or the spinning cake) of dyeing ash card, and certified products are 〉=3 grades (aberration 3.4 between each cylinder or the spinning cake) of dyeing ash card.At present, the method of inspection of viscose filament yarn dye uniformity is to extract by a certain percentage test sample with the turnout size, after test sample is made into suspenders, dyeing, compare with ash card standard specimen with the variable color of textile color stability test evaluation, evaluate the dye uniformity grade that this production is criticized.15 spinning cakes or silk cylinder are got in daily output below 6 tons, 20 spinning cakes are got in daily output more than 6 tons or the silk cylinder dyes, and to the dyeing grade of spinning cake or the silk cylinder of sampling, are the dye uniformity grade of this batch product.But in fact, although a collection of product dyeing is decided to be high-class product or Grade A, can not guarantee that all spinning cakes of this batch and silk cylinder can both reach dye uniformity 〉=4 grade or 3.5 grades.From viscose filament yarn quality inspection and user's operating position analysis, the quality problems of the maximum that reflects are the problems of the dye uniformity of viscose filament yarn, i.e. product uneven dyeing.For such as warp with fields such as silk, hosiery yarns, application of dress materials in the system of dying during responsive look product, 3.5 grades product will cause the product dyeing flower, product rejection.Because product can not guarantee absolute level dyeing, some user of downstream draws a design one by one to the silk cylinder before use, chooses the inconsistent silk cylinder of dyeing, even if also nonvoluntary using with of the silk cylinder of adjacent lot number.The inhomogeneous range of application that greatly limits viscose filament yarn of product dyeing.
Uneven dyeing is that the restriction viscose filament yarn becomes key issue of high-end product always.High-grade viscose filament yarn at first is the even dyeing consistance to the requirement of quality, with a collection of product dye uniformity necessary 〉=4 grades, the silk cylinder can be directly used in warping and the tram of high speed loom regardless of product batch number; Next is that silk cylinder appearance forming is good, and no color differnece, fault, fracture of wire, without lousiness or few lousiness spin continuously non junction, jump silk; Be strand physical and chemical index uniformity again, except absolute index was up to standard, the coefficient of variation was very little.
Dye uniformity is difficult for the large defective that assurance is viscose filament yarn always, and this is to be caused by the characteristic of fiber itself and production technology, also is that manufacturer endeavours the problem that solves always.But owing to the multiple computer desk of viscose filament yarn production, spin position, long flow process, production run is very complicated more, and the many factors of impact is not so there is thorough change always.And existing sampling colouring method can not guarantee can both reach 4 grades of dyeing with spinning cakes all in a collection of product or silk cylinder, can't guarantee that product reaches the standard of expensive goods from dye uniformity.
Summary of the invention
